gunung bergerak???

Surah an-naml

88. And you will see the mountains and think them solid, but they shall pass away as the passing away of the clouds. The Work of Allah, Who perfected all things, verily! He is Well-Acquainted with what you do.

Plate tectonics: The main features   are:

  • The Earth's surface is made up of a series of large plates (like pieces of a giant jigsaw puzzle).
  • These plates are in constant motion travelling at a few centimetres per year.
  • The ocean floors are continually moving, spreading from the centre and sinking at the edges.
  • Convection currents beneath the plates move the plates in different directions.
  • The source of heat driving the convection currents is radioactive decay which is happening deep in the Earth.

  • The edges of these plates, where they move against each other, are sites of intense geologic activity, such as earthquakes, volcanoes, and mountain building.
  • Plate tectonics is a relatively new theory and it wasn't until the 1960's that Geologists, with the help of ocean surveys, began to understand what goes on beneath our feet.

Where is the Evidence for Plate Tectonics?

The continents seem to fit together like a giant jigsaw puzzle:

If you look at a map, Africa seems to snuggle nicely into the east coast of South America and the Caribbean sea. In 1912 a German Scientist called Alfred Wegener proposed that these two continents were once joined together then somehow drifted apart.  He proposed that all the continents were once stuck together as one big land mass called Pangea. He believed that Pangea was intact until about 200 million years ago.

so...from this facts...
we know that mountains are moving as plate move...

dah tertulis dalam al-Quran??

inilah kebenaran!!
